Note: I might just be uneducated on the subject.
When I read about web3 with blockchains, smart contracts and dapps, all sounds very promising. But once you look for any real world applications it is just some obscure things that kind of only exist to support the decentralized system. I guess that makes sense, but are there any actual real world uses for that? Like day-to-day things that make a persons life easier, not harder?
While I do agree that web3 id 99% crypto bro marketing, the fact that it requires a lot of energy is due to the kind of validation algorithm used, and this is not true for all cryptos.
Bitcoin for example use Proof Of Work, which by design requires a lot of energy, but some blockchains use Proof Of Stake validation, which requires a minimal amount of power to work
